Each service subdomain's (proxy subdomain's) virtualhost explicitly binds to all of the assigned IP addresses on a server.

SSL virtualhost configurations — such as the cpanel, whm, webdisk, and webmailservice subdomains (proxy subdomains) — use the cPanel service SSL certificate.

In cPanel & WHM version 62 and later, cPanel & WHM enables SNI functionality by default for SSL certificates on service subdomains (proxy subdomains). SNI allows multiple SSL certificates to use a single IP address and port number.

Due to these changes, Apache uses cPanel's service SSL certificate to secure websites that do not have an SSL certificate. Visitors to sites without an SSL certificate may see an SSL warning, because Apache used cPanel's service SSL certificate to secure the site.
